Abstract
A steady state model was employed for the system analysis of thermochemical c arbon dioxide splitting. The model assumed the circulating flow of reactants between a reduction reactor and an oxidation reactor. A s olid solid heat exchange r was considered to recover waste h eat between react ive material after the reduction and that after oxi dation react ors . Ceria and Zr doped ceria were assumed as react ive material. The analysis showed that the efficiencies of both reactants exceeded 10%, Zr-doped ceria indicated a higher efficiency than simple ce ria, and the efficiency was improved by the heat exchanger.
